Microsoft is planning to cut the price of its Surface RT tablets. Sources familiar with Microsoft’s Surface plans have revealed to The Verge that the price cut could occur as early as next week, with each model being cut by $150. Microsoft’s move to cut prices on its Surface RT tablets follow slow sales, and efforts to sell the devices elsewhere at lower rates. The software maker recently launched an education program to sell the Surface RT to schools at $199, and it has been clearing stock of its devices at its Tech-Ed and Worldwide Partner conferences recently. The price cut will come just days after the company hinted at replacement Surface RT and Surface Pro models during its Worldwide Partner Conference on Wednesday. Microsoft is expected to refresh its Surface Pro with a Haswell processor, and the company has been testing Surface devices with Qualcomm’s Snapdragon 800 processor.
